Abstract (en)

An optical distribution network, an optical network system, a splitter, and a method for identifying a port of the splitter are provided, to resolve a problem in a conventional technology that compatibility an existing optical network terminal is not supported when a port of a splitter is identified. The optical distribution network includes a splitter, a first optical filter, and a first power change assembly. The splitter includes at least two output ports, each output port corresponds to at least one first optical filter, different output ports correspond to different first optical filters, and center wavelengths of detection light that the different first optical filters allow to pass through or do not allow to pass through are different. Each output port of each splitter in an N<sup>th</sup>-level splitter corresponds to the first power change assembly, and the first power change assembly is configured to change a power of first service light based on received first detection light. In this way, a port of a splitter connected to the optical network terminal may be determined based on a first power of the first service light, a second power of power-changed first service light, and a center wavelength of corresponding detection light.
